What to look for when buying a 6.0. - Please add to tech file.

I know this thread exists in the 6.0 tech files already but I have something to add and I can't respond to the sticky that is there. Hopefully a moderator can add this.

Look at the turbo compressor outlet pipe where it drops down toward the intercooler next to the radiator. There is a blue rubber expansion joint. If this area appears to be oily then the oil is coming from a leaky piston ring seal in the turbo. A remanufactured turbo is $850 to well over $1000 not including installation. They sell do it yourself rebuild kits but I do not recommend this because a properly remanufactured turbo has to be spin balanced or it will wear out prematurely.

I used to work at Garrett and can tell you that you can take a turbo apart and reassemble it exactly how you had it with the same exact parts and the wheel will be out of balance most of the time. The high speed spin balancers are very accurate and sensitive to slight build changes.

I hope this helps someone.

The condition you describe is mostly caused by the CCV. If the turbo is leaking that badly there would be more than just a residue there

I'm just speaking from experience. Mine was just starting to leak at the compressor wheel.

Oh and just to clarify, the CCV (crank case vent?) is the vent coming from the valve cover into the intake before the turbo right?? There is no sign of oil in the intake prior to the compressor wheel.

Anyways just thought I'd throw my experience out there. The forum can do what it wants with it.
